Steve,
I've been told they tried a few different cams in the Z18T. The cam I use in the L20 is
288 duration, 340 lift, 114 lobe seperation with crow springs and lash pads. The L
series and Z series differ in lift at lobe and ramp angle.I think most of the cam
grinders claim that there cams are a fury copy. Nizpro say that there Z18 wouldn't rev
hard enough with the fury cam because of a to greater ramp speed so Phil Morris
designed another allowing the motor to spin to 8000rpm and produce 418hp at 7800rpm.
